2015-03-24Asynchronous LID/Resource loading for FSP systemsStewart Smith1-1/+1
This moves away from using fsp_sync_msg in fsp_fetch_data and instead using the platform hooks for start_preload_resource() to actually queue up a load and having the plumbing for checking if a resource is loaded yet. This gets rid of the "pollers called with locks held" warning we got heaps of previously. You can now boot some FSP systems without getting this warning at all. This also sets the stage for starting load of LIDs much earlier to when they're needed, improving boot time. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2015-03-17hdata: Convert printf based log messages to prlog based logsVasant Hegde1-3/+5
This patch changes all printf based log messages in the hdata/slca code to prlog based log messages. Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-02-11vpd: Use slca parent-child relationship to create vpd treeNeelesh Gupta2-142/+77
SLCA entries available through hdat have parent-child relationship of various FRUs of the system, the patch makes use of this data to create VPD nodes in hierarchial fashion. This is further useful for the user space tools like 'lshw'/'lsvpd' to plug-in the support easily on POWER.

2014-12-15Fix makefile dependency generation, especially for HOSTCCStewart Smith1-0/+2
Instead of having individual rules to generate .d, add -MMD to HOSTCC parameters, and just include the generated .d files. This fixes a few weird dependency issues. Also, make the mambo hello_kernel test depend on skiboot.lid Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2014-12-10Fix bug/warning in hdata/memory.c I introduced in f1a3a19Stewart Smith1-2/+3
Passing the wrong parameter to snprintf (sizeof(char*)) rather than actual length of the string. GCC 4.9 told us about it (and broke make check when I enabled -Werror) hdata/test/../memory.c: In function ‘add_address_range’: hdata/test/../memory.c:144:23: error: argument to ‘sizeof’ in ‘snprintf’ call is the same expression as the destination; did you mean to provide an explicit length?

2014-10-15hdata/memory.c: only prlog with PR_DEBUG most thingsStewart Smith1-8/+8
We will PR_INFO the total amount of memory, as this is just informative. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2014-10-15Only print SPIRA discovered serial port info at PR_INFO priorityStewart Smith1-3/+3
It's certainly not an error that we have a serial port, and not essential to display during boot. Odds are, you already know about the serial port. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2014-10-15decrease verbosity of logging CPU information.Stewart Smith2-17/+18
If we have an UNAVAILABLE core (e.g. garded by FSP), we *WILL* print that out with PR_WARNING, as that's probably something that people want to pay attention to. Otherwise we stick with PR_INFO, which should be enough for these kind of log messages. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2014-08-15hdata/test: Fix broken testsJoel Stanley2-1/+5
Commit e810dcbc (ATTN: Set up attention area to handle attention) broke tests, as the familiy of CPU_TO_BEXX macros are not compile time constant. hdata/test/../spira.c:60:4: error: initializer element is not constant .addr = CPU_TO_BE64((unsigned long)&(cpu_ctl_spat_area) + SKIBOOT_BASE) There is no test coverage of this code, so for now we can comment out these areas in order to allow the tests to pass.

2014-08-15{core,hdata}/test: Add prlog to stubJoel Stanley1-1/+12
We are missing a prlog for tests. This adds a dumb version that ignores the log level and uses printf to display all messages. Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-08-01ATTN: Set up attention area to handle attentionAruna Balakrishnaiah2-0/+68
At present CPU control area ntuple in SPIRA structure is NULL. ATTN component in Service Processor side checks for this field and if its empty, it logs hardcoded SRC (0xBB821410) and generates SYSDUMP. So we have 1 SRC for all failure (assert call) from OPAL side. This makes difficult to debug the issue. Service processor provides attention area interface (FIPS PHyp Attentions spec), so that we can pass SRC and user data (error message) to service processor. This will helps us identify different failures in OPAL. This patch enables attention area and provides interface (update_sp_attn_area()) to add src and user data (error message) through assert macro. Attention SRC format: 1st byte - Opal src type 2-4 bytes - Holds the address of the assert function call Signed-off-by: Aruna Balakrishnaiah <aruna@linux.vnet.ibm.com> Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
